Issues with projectM visualizations after video calibration

Able to repeat this multiple times. After calibrating for overscan in xbmc (http://wiki.xbmc.org/index.php?title=The...ion_Window), projectM visualization has errors. When playing music, it adjusts the screen to a state where part of the screen is not visible. I can provide an image if necessary, but it can be repeated easily. Using 10.1 and was able to reproduce with latest nightly.
